Ted Zlatanov commented on CASSANDRA-764:
----------------------------------------
This is why I asked for advice. "look at the code" showed me several ways to
do the task.
I see BitSetSerializer used and the bitmasks are most similar to a BitSet so I
thought it made sense to approach it similarly. ObjectSerializer simply
ensures we won't have to write ListSerializer, etc. and in fact
BitSetSerializer can be reduced to ObjectSerializer<BitSet>.
I also see ColumnSerializer but considering the purpose (bitmasks are not
supposed to be large or many; if they are then we can revisit this) I thought
serializing through a String made sense. If you're suggesting to approach it
as with ColumnSerializer, that is, to serialize the count and then the byte[]
objects individually, I can do that too.
Does the SliceFromReadCommand.toString() look OK at least? Or should I encode
it more efficiently for space?
Thanks for your help.
